Is this modeled on the lexical-let work being done for Emacs (probably  
to be merged for Emacs 24)?  If so, I wouldn't call it an extension so  
much as being compatible in advance. :-)  And if not, you should  
probably take a look at that work and make sure yours is compatible.

It definitely sounds like a good idea to me.
